pgAdmin3 LTS by BigSQL

As v1.0 of pgAdmin4 was released in September of 2016, the pgAdmin Development
Team decided to no longer support pgAdmin III with any more fixes.
We believe that pgAdmin3 usage should fade out over time and
have forked the code to include
basic support for PostgreSQL 9.6+.

In June of 2017 we have produced new Windows and OSX binaries (v1.23.0b) that work with PostgreSQL 10 that allow pgAdmin3 LTS to now support PostgreSQL 8.4 thru 10.
